Photoluminescence: Fluorescence and Phosphorescence

4.5K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

Photoluminescence: Applications

1.2K
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Bacterial Signaling

42.9K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Background:

  • Bioluminescence is the production and emission of light by a living organism.
  • It results from a chemical reaction, typically involving a light-emitting pigment (luciferin) and an enzyme (luciferase).
  • Organisms have evolved diverse strategies for light emission across various environments.

Purpose of the Study:

  • To introduce the fundamental chemical reactions underlying organismal light emission.
  • To provide an overview of the diverse biological contexts and mechanisms of bioluminescence.
  • To synthesize current understanding of how organisms produce light.

Main Methods:

  • Review of existing literature on bioluminescence.
  • Analysis of biochemical pathways involved in light production.
